Definitions

  • the invention relates to improvements to seed seeders under mulching, in particular to unwinding devices and film cutters, as well as to soil the film at the end of the sowing row.
  • Seeders under mulch called plasticizers
  • plasticizers are often equipped with a film cutter actuated at the end of the seeded row, the free cut of the laid film, like that which will start the next row after the seed drill is turned, are free or left free and the film is thus not held on the ground by its edges which are buried or covered in a hurry and manually with a little soil to keep them on the ground. Soaking is compulsory and inconvenient especially for the start of the second row, in particular in case of wind because the free film floats in the air and is difficult to maintain in order to be correctly placed on the ground.
  • plasticizers are constituted by a chassis carrying respectively compacting rollers or rollers, film unwinder-applicator, as well as lifting sowing wheels with opening spiked buckets and seed hopper feed hoppers. It has already been proposed, in order to avoid the "floating" of the end of the film not laid after cutting, to provide the unwinder roller with shoes resting on the edges of said roller, but this arrangement remains practically ineffective.
  • the first object of the invention is therefore a method for leveling the cut ends and edges of the film at the end and at the start of the row with a plasticizer of the type specified above; another object of the invention relates to a device for implementing this method.
  • the end tamping method according to the invention essentially consists in ensuring close contact of the film on the downstream periphery of the unwinder-applicator, in preventing the film and the soil from going upstream on the upstream surface of the unwinder, in associating the blade or saw, rectilinear, cutting with earth retaining and spreading means, adjusting the control of the cutting member so as to allow it to come into active contact with the earth, to be coordinated for certain movements of the seed drill, the low position of the cutting member with the lifting of the sowing elements during these short length displacements, downstream or upstream, so that the earth pushed by the cutting member and the means of restraint and display cause the soil they entrain to be placed on the end of the film at the end of the mulch row or to mulch.
  • the invention also relates to a certain number of characteristics making it possible to lighten the seed drill and to cilitate its maneuver, reducing both the manufacturing costs and maintenance and use.
  • a film unwinder-cutter device adaptable to various types of plasticizers, is characterized in that on the machine chassis are mounted on the one hand a cylinder carrying the roller of the film to be unrolled, on the other hand a cylinder practically tangent to one of the generatrices of the cylinder carrying the film and applying said film to the ground by acting as a sealing roller and finally that the latter unwinding roller carries at each end of its axis a arm pivoting freely around the latter, a saw blade being arranged at articulation between the second ends of these arms, means such as a jack carried by the frame being provided to keep the saw away from the film or to apply it against the film for its cutting, an elastic element acting on said means to avoid the unwelcome effect of obstacles from the ground on the regular cutting of the film at the end of the row, means acting in any case during cutting to em catch any awkward position by the film, that is to say to prevent it from floating freely.
  • the means for holding the film which is not deposited on cutting can be constituted by nozzles, at least two, for blowing air supplied from the fan used for the seed distributor and arranged in the vicinity of the ground in front of the unwinder cylinder. applicator, so as to apply the film against the roller; the blowing is advantageously applied during all the work of the plastisemeuse, but it could only act during cutting, that is to say at the end of the row.
  • the means for holding the film can advantageously be characterized in that the unwinding roller has a large part of its downstream periphery in very close contact with a plate concentric to it and held elastically against it from the compacting roller, that the section is in the form of a rectangular frame, the middle of the upper side of which is actuated by a body jack which is elastically fixed to the frame of the seed drill, which two arms pivoted around each end of the unwinder shaft carry between their other ends a crazy rotating roller and connected to the cutting frame whose movements they follow.
  • FIG. 1 On chassis 1 are mounted ( Figure 1) by any known means a cylinder 3 on which the film reel 3 'is fitted; the unwinder-applicator cylinder 2 is mounted parallel to the coil 3 ′ and substantially tangent to one of the lower generatrices thereof.
  • the cylinder body 7 At each end of the cylinder 2 is pivotally fixed one of the ends of the arm 4 between the other ends of which is fixed a saw 5, for example of the mower saw type; towards the middle of the saw 5 is articulated the movable head 6 of a jack 7 fixed on the frame 1; the cylinder body 7 comprises a coil spring 8 surrounding the cylinder and which compresses against a ring 9 when an action exerted on the saw is transmitted to the cylinder, for example under the effect of a pebble or other lifting an area of film 10 at the end of the row.
  • the jack 7 in extension to bring the saw 5 against the film 10 to cut it is slightly raised which makes the obstacle "pass" by the saw 5 and immediately applies the film 10 through it. totally on the
  • FIG 2 we see the blower device for maintaining the film 10 remaining to be unrolled for resumption of row.
  • a pipe 11 brings blown air into two nozzles 12 (or more) distributed regularly with respect to the film width 10; these nozzles are arranged between the lower level of the unwinding cylinder 3 and the ground, being oriented so that the respective outgoing jets apply the film against the surface of the cylinder 3 after the line of cutting 13 traced by the saw 5.
  • the operation of the device is as follows: when, driving in the direction of arrow F, we arrive at the end of the row, the driver must raise the machine; to this movement corresponds the control of the jack 7 which pushes the saw 5 by the head 6 to apply it against the film 10; if the ground is normal, the pressure of the saw 5 causes the film to cut along line 13, the wind coming out of the nozzles 12 applying the hanging part of the film, after cutting, backwards, against the surface of the sealing cylinder 3 , and therefore allows its easy unfolding at the start of laying on the next row.
  • the sowing is not pneumatic, it is advantageous to equip the plasticizer seed drill with a particular fan in order to thus ensure "control" of the film when cutting.
  • the seed drill shown is of the known type comprising an assembly (compacting rollers 1, film holder 3, film applicator unwinder 2, film cutting device 4 with jack) carried on a frame hookable by a "three-point" device 5 to a tractor on the one hand and extended by a part “seed drill with pins", which will be designated as “sower unit” 6, with distributor 7 driven synchronously with the rotation of the opening pins 8 and mounted inside the seeding wheel 9, the seeds being brought directly from the distributor into the open bottom of the bucket-pins whose beaks open and close by means of a roller rolling on a cam arranged fixed in an arc symmetrical with respect to the vertical of the sowing point and substantially parallel to the circle tangent to the bottom of the buckets ready for, or just sowing a seed.
  • the seed drill generally has four or six rows of mulching, four in the example (Fig. 3).
  • the frame 14 is here formed by two longitudinal members 15 and 16, one front and one rear, connected by fittings 17 supporting part of the at- t Elage three points to the tractor system.
  • the upstream spar 15 in the direction of travel serves as a support for the various elements on the one hand, cylinder assembly 1, 2, 3 and 4 and on the other hand seeder assembly 6.
  • two rectangular frames 18-15 -16 are provided; each is retained at the front (downstream) by a central flange 19 articulated on the chassis at 13 and by the same flange 20 at the rear; the frame 18 carries at the front a compacting roller 1 and from the front towards the rear, an unwinding roller 2.
  • a fitting 21 is mounted slightly behind the unwinding cylinder 2, provided with a vertical light 22 intended to carry the film reel roller 34.
  • the roller (s) 1 is provided with slightly concave end cheeks 23 of diameter slightly greater than the roller to eliminate the grooves in which the edges of the film will be buried, with in front of said cheeks an adjustable razor 24 for forming grooves.
  • the compacting and unwinding rollers are mounted by their respective shaft ends mounted in chairs provided on the frame.
  • the flange 20 at the rear of the frame is equipped with a crank 25 with spring allowing the frame to descend or rise to give the film a correct tension on the ground.
  • the shaft 3 'on which the film reel is engaged has its ends guided in the vertical light 22 so that the film roll can only move by unwinding from above below or vice versa.
  • the frame On the ends of the shaft of the compacting roller 1 are articulated two arms 28, the free end of which acts by means of a spring 26 'on a plate 26 curved in an arc of a circle fitting perfectly at least about the upper front quadrant from roller 2; this plate 26 is thus well applied against the film which takes place from the roller 3, which avoids any winding of the film otherwise well stretched by the pressure adjusted by the plate springs and by the pressure on the ground adjusted by the crank 25.
  • the frame Behind the film holder and unwinder, the frame carries a film cutter device 4 formed in the form of a rectangular frame 27, preferably of metal tubes, the upper side of which is articulated in its middle on the piston head.
  • a jack 4 ′ the other end of which is fixed to the chassis and the lower side of which is split to receive the cutting member (saw or cutting blade); the vertical sides of the frame 27 are articulated on arms 28, the other end of which is pivotally mounted on the ends of the shaft of the unwinding roller 2. Good guiding of the cutting member is thus ensured when the jack 4 ′ is actuated to raise or lower the saw 4 "; a spring 28 'interposed between the body of the jack and its attachment to the frame allows the saw to be retracted when it encounters an obstacle on the ground, thus preventing any risk of deformation.
  • This articulated connection between the cutting member and the unwinder-applicator roller is advantageously such that the saw is, for the usual dimensions of the unwinding rolls, at about ten centimeters from said roller.
  • the invention on the one hand by a scraper 29 extending over the entire length of the film cutter on which it is articulated by an edge, its other edge resting on the "filmless" part of the unwinder roller 2 (thus preventing the earth and the film once cut to go up on this roll), and on the other hand a small roll 30 mounted with free rotation around the free end of two arms 31 whose other end is fixed in two symmetrical points of the edge carrying the saw, so as to be applied and roll on the ground when the film cutter is lowered under the action of the jack.
  • Each end of this small roller 30 carries, coaxially, an earth deflector 32.
  • a press wheel 33 for each row and followed by a razor 34 for covering the edges of the film.
  • the sowing unit On the rear spar 16 of the main chassis is mounted the "seeder" assembly of the seeder, that is to say the wheels 9 with buckets - pins, the hoppers 36 containing the seeds with their distributors 7 in the wheels and their members drive and adjustment.
  • the sowing unit advantageously has the following particular characteristics, which will be seen that they significantly reduce the total machine, its ease of construction and its price.
  • the bucket wheel 9 consists of a circle 105, against the periphery of which are fixed hoppers 106 open towards the center of the circle, extended by a triangular plate extending outwards the plane of the circle to form the fixed part of the pin 104; on the edge, not in contact with the circle, of each hopper is articulated, around a hinge, the triangular hollow beak of contour identical to that of said rectangular plate to be applied to it in the closed position of the pin, a arm 102 being fixed on the spout and provided at its free end with a roller 103; this roller rolls on a fixed cam 103 'provided in the lower part of the assembly, substantially concentric with the circle 105 from a point slightly in front of the vertical of the seeding point passing through the center of the circle and extending approximately to the end of an arc covered by three pins 104.
  • the walls of the hoppers 106 are in contact to avoid any loss of seeds brought from the distributor 7.
  • the latter is disposed inside the circle of the wheel constructed with three spokes 107 connected to the hub on the drive axis; it is slightly offset towards the front.
  • the seed wheel 9 is mounted in a frame 35 bearing bearings for the axle shaft of the wheel.
  • the front part of the frame is articulated on the side member 16 of the main chassis by means of flanges to allow the seed wheels to be raised and lowered.
  • Each hopper support 37 36 is provided with a chain 38 connected to a jack 39 mounted on the fittings 5 for attaching the three-point suspension, which makes it possible to raise or lower the sower unit on the ground, independently of the set cy - liner, decoiler, film cutter.
  • each seed wheel frame carries in its axial extension a press wheel 108 adjustable in height under the action of a crank 109, in a slide fork.
  • the seeding wheels 9 are driven from a single driving wheel 110, mounted at the rear end of a bar 111, the other end of which is fixed to the beam 16 of the main chassis in the middle of that - here and equidistant from the two "inner” seeders; the driving wheel drives by pinions 112 and chains 113 pinions 119 mounted on the shaft of each of the two inner wheels the other ends of the respective shafts of these wheels driving by gimbals 114 the two outer sowing wheels.
  • the single drive wheel is mounted in the middle of the sower unit and directly drives the two inner sowing wheels closest to them, each distributor being driven synchronously with its wheel.
  • the single driving wheel 110 at the rear also plays the role of stabilizer of the seed drill thanks to the thrust of the third point of the coupling on a pendulum with spring exerting a certain pressure on said driving wheel in combination with the front rollers.
  • the rear wheel resting on the ground, facilitates the transport of the seed drill from one field to another.
  • the operation of the drill for TERRA e g at row ends is as follows (Fig 3 to 7.):
  • the operator simultaneously controls the lifting of the sowing unit 6 (with its seeding and sealing wheels) from its place by actuating the cylinder of the fastening system fittings acting on the hopper chains and simultaneously the cylinder 4 of the cutter film 4 ', the saw 4 "guided by the arms 28 of the unwinder 3 descends a few centimeters and cuts the film.
  • the operator raises the whole machine by the three-point suspension, and advances it by about 50 centimeters
  • a dial indicating the length provided for such a movement of the seed drill in one direction or in another.
  • the soaking process "at the end of the row” then continues "symmetrically" in the previous phase: the operator lowers the assembly (1,2,3,4) so that the rollers rest on the soil and that the 4 "saw enters the ground; it advances the seed drill about 50 centimeters so that the free part of the cut film (which constitutes the beginning of mulching to be carried out on the new row) which, thanks to the plates 26 hand Yours, had rewound itself on the unwinder and possibly on the reel, is correctly applied on the ground, with simultaneously a suitable covering of the end of the mulching to be done, by the earth pushed in the displacement.
  • the operator then only has to lower the sower unit 6 and simultaneously the saw 4 'lifts up and processes the new row.
  • the methods and devices according to the invention are therefore well suited to the problem of soil at the end of the row of seeders under mulch.
  • the lightened wheels improve the quality and speed of the maneuvers.
  • the method is adaptable to known seeders, in particular to those fed by the open bottom of the buckets. The manufacturing and use prices, the ease of access of the elements, are greatly improved.
